Thanks for posting this -- I recently had to re-do my setup and used your package and this guide to get back up and running. Worked like a charm. Only one thing you might want to add to the instructions above (if you don't already have it installed) is to run: /home/pi/oprint/bin/python -m pip install keyring

before your step 3

Thanks @ericli1018! I'm glad people find this plugin useful but regret that I have been unable to maintain it. I realize this has resulted in frustration for some users. So, I appreciate the effort you have put in to posting fixes.

I dont know how to "maintain" this... but i got it working under the 0.15.1 with little effort... your core plugin is hidden from the plugin list.

Thanks to @anoved for original plugin -- wish you had time to maintain it (but I understand). :-( Thanks to @ericli1018 for the updates!

For others arriving here because they are having trouble installing, I just did a fresh install starting with Octopi 0.15.1, and here's the sequence that worked for me:

1. Installed Octopi 0.15.1 per instructions.
2. SSH'd and updated OS (i.e., 'sudo apt-get update" and 'sudo apt-get dist-ugprade')
3. Updated Octoprint to current version (1.3.9 at moment).
4. Installed Email Notifier via Octorprint plugin UI, using master.zip provided by @ericli1018: https://github.com/ericli1018/OctoPrint-EmailNotifier/archive/master.zip
5. SSH'd and run following commands at prompt:

   source ~/oprint/bin/activate
   pip install yagmail
   pip install keyring              (note: be patient, this takes a while....)
   pip install keyrings.alt
   python
   >>> import yagmail
   >>> yagmail.register('my.email','my.password')
   >>> ctrl-D to exit
   sudo shutdown -r now

After restarting, Email Notifier was able to successfully send email. Hooray!

I put off upgrading my pi to a pi3b+ for a long time, because I was concerned I wouldn't be able to get this plugin working. Sure hope someone with the necessary skills will be able to step up and fully take over maintenance -- would be nice to see keyrings.alt eliminated, and to perhaps see a better installation process or at least official installation instructions for the yagmail/keyrings/register stuff.
